T 0 all 'w from t may concern Be it known that l', CLARENCE H. Brun,

spanien,- a. citizen ofthe TJnit'ed States? residing)` at Sparta, inthe county of Kent and State ofxlllichikgan, have invented new and useful Improvements in Machines for liefacinglfa'lves1 of which the following l is a specification- The present .invention relates to machines feriefacing valves, suchl as are employed in internal-combustion engines and the like;

and itsobject-is generally, to provide amachiney of, 'that character whichV may be eco-y nomically manufactured and readily and easily operated; andy, more particularly to provide such a Amachine `improved ink various respects hereinafter appearing; and furthen to provide improved means for moving'the valve-rotatingxmeans of" such-a machine into and out-of operative enoae'enient with. the y Woilr; and further,- rto provide improved means for' adapting sucha machine to'differentkinds Ofsuoh valves and further, to provide `improved @Sensi for adapting' such a i machine to valves havingv stenisof different diameters; and further, to providepan improved mounting for the operating; crank of such a machine; vand further, to provide improved meansy forejectingl a bushing in which the-valve stem rotates from such a machine;A and/ further, to provide improved meansfonejecting the valve from such a machine.

These and any other objects hereinafter appearingare,attained by and the invention finds preferable enfilbodiinent -in,wthe structure hereinafter particularly described and illustratedfbyth'e accompanying drawings, in Which.:-.,.

iication, my valve re-kfacinp; machine hasy a body' 1 havingan opening 2 adapted toreceive the stem 3 of the valve l Whose circular bevelled edge yportion 5 (which contacts 'the valve seat) is to bere-faced- Cutting means are kcarried in connection with the body y1, such means in the construction illustrated being` the oppositely disposed cut- :gers or bits 6 seated in vertical slots? in the block y8 and secured in such slots by set iscrevvs 9. This block is desirablyremovably secured to the body 1 in any suitable manner, as by the downwardlyeirtending lugs 10 of saidbloclfr, seated in socketsiill in the body 1. An arm 12 isswingably mounted. on the body 1k at on one side of the opening 2 andvjmay be svvungto 4the Yoperative position ofthe machine shownin the drawings" and secured in suchlposition by', suitable A particularly shown in Figure 6) g said 'shaft I also has acollar 22 Withspaced lugs 23 adapted toengage in the spaced soclzetsf24 of sucha valve 4 as issliowninFigure 2. This collar 22l yis movable longitudinallyy the `shaft to and from a position shown in Figure 2 in which position :Y it is operative, yandis secured in suchpositionjasby a ,cotter ypiii The ic'otter pin being removedE the collar may be detached, whereupon the rib 2O may be employed'to engage the lrerf 21. of such valves as are shown in Fig'ure 6.`

A, crank 26for lrotating the shaft`18 'may beswingably mounted at 27 on one side of theshafjts axis and thus renderedturnabley to the position shovvnjin'Figure 2jvherein it engages; lbetween, I lugs 28,*` 29 ,carried 'by g las? the shaft at the opposite side of its axis from the mounting 27. By this arrangement the crank may be turned over to the left hand side of the machine shown in Figure 2 when not in use, in which position the machine is more compact and occupies less space.

The opening 2 is ot sufficient diameter to receive a bushing 30 iitting therein7 and provided with a central bearing 3l in which the valve stem 3 rotates. Bushings or the same outside diameter but whose bearings 3l. are

of different diameters being provided., valves having stems or different diameters co1re sponding to the bearings 8l of such bushings may be re-faced on the same machine. The opening 2 is internally threaded at 32 adjacent its lower end, a threaded member 33 turning on said threads. This member 33 has an axial bore 34 receiving a stop-.member 35 bored at '36 to receive the valve stem 3 and operating to limit the downward movement of said stem; this stop being adjustable by turning the member 33. The reduced lower portion 37 of this stop member 35 extends through the opening 38 in the lower end of the member 33 and may be moved upwardly by hand or by a blow from a hammer, whereupon the valves re-aced portion 5 will be ejected from the cutters; and the upward movement of the member 35 continuing, its upper edge 39 will then abut on and eject the bushing 30 from the opening 2. Before thus ejecting the bushing; the chips resulting from the re-acing operation may be swept or blown out through the oriices 40 through the wall of the opening 2 so that they may not fall into the bottom portion of said opening. l

The shank portion 4l of the body l is squared as shown and is non-turnably seated in a square socket 42 in the mounting member 43 which may be secured to the edge of a table or bench 44 by a screw 45.

The invention being intended to be pointed out in the claims, is not to be limited to or by details of construction of the particular embodiment thereof illustrated by the drawings or hereinbefore described.
